Lawn-mowing is a physical change, whereas the grass dying is chemical.
Cutting doesn't change the chemical composition.
It is a physical change because paper is still paper and its the same even if it has been cut. If the paper were say to get burned it would be chemical change because it is no longer paper and it has a different form.
Mowing a lawn is a physical change because the act of cutting the grass does not alter its chemical composition. The grass remains the same material, just physically altered in size and shape.
Diamonds cutting grass would be considered a physical property. This is because the ability to cut grass is a physical characteristic of the diamond based on its hardness and structure, rather than a chemical change in the diamond itself.
Mowing the lawn is a physical change because the grass is only being cut into smaller pieces, but its chemical composition remains the same. The act of cutting the grass does not alter its molecular structure.

Mowing is a mechanical process, not a chemical reaction.
Neither. It is a physical activity. See the link below for an explanation of physical and chemical properties.

grass growing is a physical change.
It is a physical change because it is still grass. Nothing new has been made.
Mowing the lawn is a physical change because it involves cutting the grass without altering its chemical composition. The grass remains the same substance; it is simply reduced in height. Physical changes affect the form or appearance of a material, while chemical changes involve a transformation into a different substance.
it is a chemical change
Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!
